On Entertaining Ghosts

O, most convenient ghost: I find
I entertain you in my mind.
So come and sit, we'll chat a bit:
Your cup will overflow with wit.

Frustrating though you are, my friend,
I like your haunts: they shall not end.
Whereas we danced to: "Hope, Disbanding,"
Now we dance to: "Understanding."

That's your cappuccino, there.
Need more sugar? Take your share.
Nothing's worse than bitter drinks--
Except, a bitter heart, methinks.

Time--the greatest sweetener--
Rightens things misthought before.
One nervous, gnawing night in bed
I knew: I'm living in my head.
